This cave has gated access. Access is administered by MLCMAC on behalf of NRW.
See the contact information page for details of how to obtain a permit and key.
Access rules for Agen Allwedd.
Permit/key application form
No tackle is required for the main routes, although a 10 metre handline is recommended
for the climb down at Keyhole Chamber, where P-bolts are installed. These are the only
official fixed aids in the cave. The integrity of in-situ ropes is not not guaranteed
and you use them at your own risk.
Certain sections of the cave are prone to flooding. In moderate
flood, the area around 3rd Boulder Choke sumps, and in heavier flood
conditions 2nd Boulder Choke and the narrow section of Turkey Streamway
above Northwest Junction become impassable.
Lower Main Stream becomes impassable and can sump upstream from Southern
Stream Passage junction. Also, Maytime floods dramatically.
